I'm Dense from CetraSanctuary on Bahamut.
This person wishes to change servers for an EU-timed LS, and also change their userID to Vyvyan. They expressed interest in playing on the same server as an IRL friend named Jeffy on Bahamut, who I've not been able to contact at all.
Their reference LSes from Carbuncle are the following:
Legacy, RoninMoogle, KuroKumoClub and Dotunderscoredot
